# Single source of truth: fastlane/metadata/android/<locale>/ feeds BOTH the
# official F-Droid repo (harvested from source automatically) and the
# self-hosted repo. This script transforms the fastlane layout into the F-Droid
# "localized" layout that the self-hosted `fdroid update` consumes, so we don't
# maintain two copies.

#   usage: fastlane_to_fdroid_localized.sh <fastlane_android_dir> <out_localized_dir>

#   changelogs/<versionCode>.txt -> changelogs/<versionCode>.txt
